c. subsistence
d. desalinated

The correct answer is c. subsistence.

Middle Eastern farmers till this day use this type of farming which is practically providing enough for yourself and your family. This type of farming is practiced because of multiple reasons, in the Middle East the biggest reason is the climate. The climate in the Middle East makes a place not very suitable for agriculture apart from the places were the big rivers are flooding. It is mostly a desertous place, there's very little precipitation, the temperatures are extremely high, in most part there's lack of water, and the soil is of very low quality. So the farmers are trying to produce what they can just for them and that takes them a lot of effort, and even if they want to produce more it is impossible in most of this region.
